FLY-TRAP ATTACHMENT.

Specification of Letters Patent.

Patented Oct. 18, 1910.

Application filed June 20, 1910. Serial No. 567,923.

To all whom it may concern:

Be it known that I, HENRY C. Kossow, a citizen of the United States, andresident of Milwaukee, in the county of Milwaukee and State ofWisconsin, have invented certain new and useful Improvements in Fly-TrapSash Attachments; and I do hereby declare that the following is a full,clear, and exact description thereof.

My invention consists in what is herein particularly set forth withreference to the accompanying drawings and pointed out in the claims ofthis specification, its object being to provide simple, economicalfiy-trap attachments for window screens, screen doors, and glazed sash.

Figure l of the drawings represents an elevation of a fly-trap inaccordance with my invention partly broken away and detachably connectedto a fragment of a windowscreen; Fig. 2, a sectional view indicated byline 22 in Fig. 1, and Fig. 3, a perspective view of the trap detachedfrom the screen.

Referring by numeral to the drawings 4 indicates a stile, 5 the top railand 6. the wire-netting cover of an ordinary windowscreen. Engaging astaple 7 and preferably collared angular hooks 8 driven in thescreenframe from the inner side of same, adjacent to an upper cornerthereof, is a flat triangu lar frame of suitably joined sheetmetalstrips 9 and 10. The side-strips 9 are folded upon a triangular sheet IIof wire-netting that opposes the base-strip 10, and this strip 10 isprovided with an outwardly extending, longitudinally slotted andpreferably lipped flange 12. This base-flange fits between the stile andthe top rail of the screen crosswise of the adjacent corner of the same,and its lip 13 abuts the screen-cover. One of the strips 9 is preferablycaught in the fold of the other, at the unction of the two, and both ofsaid strips are preferably caught in endfolds of the strip 10, as shownin Fig. 3.

Soldered or otherwise suitably secured to the inner side of thebase-flange 12 of the triangular frame, in register with the slot 1& ofsaid flange, is the base of a wire-netting cone 15 open at its apex andof preferably finer mesh than the sheet 11 of similar material, saidapex and that of said triangular frame being in line.

Flies traveling upward upon the inside of the screen-cover 5 find theirway through the cone 15 into the space between it and said screen-coverwhere they are trapped, but as a corner aperture 16 of suitable area isprovided in the aforesaid screen-cover, the trapped flies eventuallyfind their way out through the same.

One of the hooks 8 is shown in Fig. 1, turned clear the strip 10 of thefly-trap attachment above specified, and said hook being 1n thisposition said attachment may be readily disengaged from the other ofsaid hooks and the staple 7 whenever necessary or desirable, but it maybe permanently secured in connection with the'screen-frame by anysuitable means.

\Vhile I have particuarly described the aforesaid attachment inconnection with the sash of a window screen, it is just as applicable toa screen-door or glazed windowsash, the screen material or glass of thesash being provided with a fly outlet within the confines of saidattachment.

I claim:

A fly-screen sash-attach1ne11t comprising a flat triangular framehaving a longitudinally slotted outwardly extending baseflange that fitsbetween a stile and rail of the sash crosswise of the adjacent corner ofthe same to abut the cover or glass thereof in which a fly-outlet isprovided; a sheet of wire-netting closing the triangular frame, and anopen apex wire-netting cone secured at its base to the inner side ofsaid flange in register with the slot thereof.
